Computer video card problems-very technical-can you help?

I have a evga Nvidia GeForce 6200 AGP video card with 256MB RAM, and it is causing some serious problems. When i start my computer, sometimes it would display funny colors or the mouse pointer was screwed up or the screen would flicker and go blank, then a few seconds later the hard drive would give out and cause the rest of the computer to restart. It happens different times, sometimes immediately after the computer starts, sometimes shortly after logon, sometimes when i run more than one program. Now i finally figured out, if i turn off all hardware acceleration it runs fine displaying web pages and doing light work on ms word.(minus hardware accel for games...) I tried moving it a notch and it just does the same thing and make all my drives fail. I've already assumed its a serious problem with the video card, Windows XP error reporting says its an "infinite thread" on the video card driver, and the website suggests it's a problem with the device. is there anything I can do besides getting a new one? This computer isn't worth a new card. I am running Windows XP SP3, latest NVIDIA drivers (the control panel options dont work with no hardware accel though).



If its any help, i have the BIOS settings pertaining to the card on these:



Video BIOS shadow Enabled

Video RAM Cacheable Disabled

AGP Aperature Size 128MB

AGP Mode 8x

AGP Fast Write Enabled

AGP 3.0 Calibration Cycle Enabled



Any help would be appreciated :)|||Chances are unfortunately it is the actual card. How long have you had it?



I know its not what you want to hear, but you will probally have to get a new one.



You could check my PCI-e slots and the actual card, make sure there's nothing out of the ordinary there.|||Your power supply may not be strong enough to power all of the components on your motherboard at once. There is probably not enough to run any video acceleration.
